Guinea impatiens plant named &#39; Vicky &#39;

ABSTRACT

A new and distinct cultivar of New Guinea Impatiens plant named ‘Vicky’, characterized by its light pink and bright red bi-colored flowers; moderately large round flowers; freely flowering habit; early to medium flowering response; compact, low-growing and uniformly mounded plant growth habit; very dark green-colored leaves; and resistance to Powdery Mildew.

BACKGROUND OF THE INVENTION

[0001] The present Invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the name ‘Vicky’.

[0002] The new Impatiens is a product of a planned breeding program conducted by the Inventor in Goennebek, Germany. The objective of the breeding program is to develop new Impatiens cultivars with large rounded bi-colored flowers and dark-colored foliage.

[0003] The new Impatiens originated from a cross made by the Inventor in 1997 of an Impatiens hawkeri seedling selection designated as code number 2, not patented, as the male, or pollen parent, with an Impatiens hawkeri seedling selection designated as code number 18, not patented, as the female, or seed parent. Both selections are proprietary and used only in the Inventor's breeding program. The cultivar Vicky was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Goennebek, Germany in the fall of 1997. Plants of the new Impatiens differ from plants of the parent selections primarily in flower and foliage color.

[0004] Asexual reproduction of the new cultivar by terminal cuttings taken in Goennebek, Germany, by, or under the supervision of the Inventor, since the fall of 1997, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

[0005] The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Vicky’. These characteristics in combination distinguish ‘Vicky’ as a new and distinct Impatiens cultivar:

[0006] 1. Light pink and bright red bi-colored flowers.

[0007] 2. Moderately large round flowers.

[0008] 3. Freely flowering habit.

[0009] 4. Early to medium flowering response.

[0010] 5. Compact, low-growing and uniformly mounded plant growth habit.

[0011] 6. Very dark green-colored leaves.

[0012] 7. Resistant to Powdery Mildew.

[0013] Plants of the new Impatiens can be compared to plants of the cultivar Tagula, disclosed in U.S. Plant Pat. No. 10,302. However, in side-by-side comparisons conducted by the Inventor in Goennebek, Germany, plants of the new Impatiens differ from plants of the cultivar Tagula in the following characteristics:

[0014] 1. Plants of the new Impatiens have smaller leaves than plants of the cultivar Tagula.

[0015] 2. Flowers of plants of the new Impatiens are positioned above the foliage whereas flowers of plants of the cultivar Tagula are positioned within the foliage.

[0016] 3. Petals of plants of the new Impatiens are more rounded in shape and apices are not as deeply incised as petals of plants of the cultivar Tagula.

[0017] 4. Flower color of plants of new Impatiens is light pink and bright red whereas flowers of plants of the cultivar Tagula is close to white and bright red.

[0018] Plants of the new Impatiens can also be compared to plants of the cultivar Dark Twilight, not patented. However, in side-by-side comparisons conducted by the Inventor in Goennebek, Germany, plants of the new Impatiens differ from plants of the cultivar Dark Twilight in the following characteristics:

[0019] 1. Plants of the new Impatiens are more compact and more freely branching than plants of the cultivar Dark Twilight.

[0020] 2. Leaves of plants of the new Inpatiens are darker green in color than leaves of plants of the cultivar Dark Twilight.

[0021] 3. Flowers of plants of the new Impatiens have a stronger bicolor contrast but a less distinct star pattern than flowers of plants of the cultivar Dark Twilight.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

[0022] The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Impatiens. The photograph comprises a top perspective view of a typical flowering plant of ‘Vicky’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

[0023] The cultivar Vicky has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, water status and/or fertility level, without, however, any variance in genotype.

[0024] The following observations and measurements describe plants grown in Hillscheid, Germany, under commercial practice in a glass-covered greenhouse. Two groups of plants were used for the following description: one group was grown during the spring of 1999 and the other group was grown during the spring of 2000. Both groups of plants were planted in early March in 12-cm containers and grown with 20° C. minimum day/night temperatures. The following observations and measurements were taken when the plants started flowering or about 10 weeks after planting rooted cuttings. In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
